Talked to my buddy in finance he says this mistake happens from time to time I'm kinda shocked you'd think they'd catch a $19,000 mistake or a $135,000 mistake...But they don't...He said when he first started he saw a case where the Army had hired a local country, they had agreed on $150,000 for some work, they sent in $300,000 instead (I guess they hit enter twice)

O well shit happens, I once had a older gentleman come into my office to buy a Focus (price of $18,000 for the model he picked) hit transit (he was paying cash)

He calls me up two days later and goes "um, did I buy one or two cars" I respond "if you want we can make it 2..." he goes "um, no thanks I think you overcharged me" i went "by how much?" he goes "$18,000" I go "opps" check the system guy has a $18,000 over payment. We of course returned that portion back ASAP.

Although he said the system does have it's limits anything over a million requires approval by a 2nd party, said he had a case where a Pvt wasn't getting any money...They checked the system it's because his pay was set at 1.4 million monthly and the system wasn't processing the payment...
